An identification circuit () recognizes optical probes (A,B) of different scanning types that are connected to a light source unit () and a control device (), the frequency of the drive signal of a control circuit () for driving a scanner inside the optical probe is varied by this recognition signal, corresponding drive signals are applied to the optical probes connected, the scanner of each probe is scanned, and two-dimensional optical information is imaged by an imaging device () and displayed on a monitor ().

Optical scanning probe system

A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated or otherwise activated using the secondary battery as a driving power source to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument by induction from the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged without compromising sterility.

A light scanning optical device comprises a light source for entirely illuminating a subject, a converging optical system for converging light returning from a specific minute region of the subject, a light detector for detecting the light converged by the converging optical system, and a scanning mirror for scanning the minute region, the scanning mirror being produced by a semiconductor manufacturing process.

An endoscope apparatus capable of preventing occurrence of problems trouble attributable to exhaustion of a battery has an endoscope and a battery-powered light source. The endoscope has a light guide fiber bundle over which illumination light is propagated. The battery-powered light source is freely detachably attached to the endoscope, and includes an illumination lamp and a battery. The illumination lamp supplies illumination light to the incidence end of the light guide fiber bundle on which illumination light falls. The battery serves as a power supply causing the illumination lamp to light. At least one of the endoscope and battery-powered light source has an indication unit for notifying a user of the amount of electrical energy contained in the battery.

Endoscope device and operation apparatus

A light scanning device has a tip structure which includes a light scanning part connected to a light source, and which is insertable into a body cavity and is formed so as to be water-tight. A controlling part controls the light scan through the tip structure, and the tip structure and the controlling part are also connected to each other in a water-tight manner by a slender tube through which a plurality of electrical cables pass. An electric connector is fixed with the proximal end portion of the tube in a water-tight manner, and is electrically connectable so as to be water-tight with and removable from this controlling part.

A low coherence beam emitted by a low coherence light source is split into two portions. One portion is transmitted from the outward end of a first single mode fiber via a detachable connector to a beam scanning probe, and then to a biological tissue; and the other is transmitted from an optical coupler placed midway along the light path via a second single mode fiber to a light path modifier. The light path modifier includes a galvanometer mirror to modify the light path length in accordance with a scan range, and a uniaxial stage to adjust the light path length to absorb the variation in lengths of different beam scanning probes. The light path is adjusted by the uniaxial stage such that the beam interference is detected for the scan range, to ensure stable acquisition of tomographic images.
